Hi guys so here's the deal. I have a 2003 Lancer ES 5 speed with 115k on the clock. Everything works well apart from a few little niggles here and there.

There is one problem that has concerned me since I got the car 2 years ago and that is that the clutch chatters in a very specific way. The clutch will only chatter when I start in first at about 1400-1900 RPM, while I am rolling between 3-10 MPH. And it only happens when the car is fully warmed up and I have been driving for a while. It doesn't happen when I start from a dead stop or when I am rolling and the engine is cold.

The clutch feels great, tight and grabs well so it isn't a worn clutch as far as I can tell. It just judders and shakes the whole car when it happens. Needless to say I have learned to start out most of the time to avoid the chatter, but every once in a while I forget and it happens.

Not a huge problem, just annoying as hell! Has anyone experienced this before? Or has any idea what is going on?

Thanks!

 

could be loose or broken engine mounts...

 

That's kind of what I was thinking, but I was unsure because it only happens in one specific situation. Wouldn't the judder happen in 1st gear regardless of the motion of the car or engine speed if a mount was loose or broken?
